Solids, liquids, gases, and plasmas: these words should be quite familiar to you because they are the four phases of matter, which are simply the different forms matter can take on. What's neat is that many substances can exist as more than one phase. Take water, for example: water can exist as a solid (ice), a liquid (liquid water), and a gas (water vapor).
The difference between these states is the amount of energy. Solids have the least amount of energy, which is part of why their particles hang so tightly together. Liquids have more energy than solids, which is why they will take on the shape of their container but only up to the surface.
Gases have even more energy than liquids. So much more in fact that their particles spread out to fill the entire space of their container. Gas particles have so much energy that they just can't keep still. They fly around in all directions, putting as much distance as possible between themselves and the rest of the gas particles.
Plasmas are ionized gases, and in their natural form are uncommon on Earth. You've seen them as man-made things, like neon signs and fluorescent light bulbs. But in the rest of the universe, plasma is actually the most common phase of matter! Most stars are plasma, as are the northern lights you see around the Polar Regions. Plasma only exists under certain conditions though, so we'll end our discussion of it here for this lesson.

The third type of plate boundary occurs where tectonic plates slide horizontally past each other. This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.
The correct option is (C) A digestive system with a single opening.
Which characteristic is shared by both cnidarians and Flatworms?
- The class Soft-bodied stinging creatures like corals, sea anemones, and jellyfish are categorized as cnidaria. Numerous aquatic settings contain cnidarians. Sea anemones can be found all around the world, from the equator to the freezing northern regions and from small tide pools to the deep ocean floor.
- Simple flatworm-like creatures belong to the phylum Platyhelminthes. Flatworms are parasites that live in or on other animals and are found on land, in fresh water, and in the ocean (e.g., tapeworms). Flatworm parasites can harm or even kill the host organism when they dwell on or inside of other species, including humans.
- Although flatworms, like cnidarians, have a digestive system with only one opening into the digestive cavity, the cavity in independently living marine flatworms branches into every section of the body.
